Description

The VS1053 USB Music Player is a cost-efficient low component count MP3 + WMA + AAC + HEAAC + Ogg Vorbis + Flac + MIDI + WAV music player. It uses a single VS1053 DSP chip for audio decoding and a user interface. Music files are stored either on an SD card or on-board FLASH memory. A high speed USB interface (480 Mbit/s) is provided for file transfers. SDHC cards larger than 2 GB are supported. The USB interface is provided by a generic USB SD card reader IC (many vendors available).
